Change the kernel mmap interface so that the offset to map is an
...
"off_t" and the return value is a "paddr_t" to allow mappings
at offsets past 2^31 bytes. Somewhat inspired by FreeBSD, which
only changed the offset to a "vm_offset_t".
Includes updates for the i386, pc532 and sh3 mmmmap from Jason Thorpe.

First-cut support for P4 framebuffers. Currently supports P4 variants
...
of bwtwo, cgfour, cgsix, and cgeight. Includes support for attaching
the overlay plane of the cgfour and cgeight as a bwtwo instance (a'la
SunOS).
P4 register descriptions, cgfour driver, and cgeight driver partially
derived from OpenBSD.
This code may still need polishing.
